Cold water meter multi-jet DN50, pulse output, Dimm (meters) -ref. DHM1000-50300

Cold water meter multi-jet DN50, pulse output, Dimm (meters), water metering with pulse output, distributed by DIMM.

Why meter water

Metering water means controlling it: metering and sub-metering allow you to track consumption by point of use, fairly distribute charges between occupants or workshops, detect leaks by comparing readings and bill based on actual consumption. A reliable meter with pulse output integrates into building management systems (BMS) or remote reading systems for automated monitoring without on-site visits.

Principle

This multi-jet water meter measures potable or slightly contaminated water consumption with excellent accuracy, even at low flow rates. With pulse output, it covers a wide range of diameters (DN15 to DN50) for domestic and industrial applications.

Operation

The multi-jet principle distributes water onto the turbine through multiple orifices, improving accuracy and longevity compared to single-jet designs. Dry dial, magnetic transmission anti-fraud, R=80 ratio in horizontal position, externally adjustable sealed screw. Pulse output (12 values) feeds remote reading and sub-metering.

Applications

Applications: Sub-metering, Remote reading / BMS, Industry, Water networks.

Specifications

Key features

• Pulse output (remote reading / BMS / sub-metering)
• Dry dial with magnetic transmission (anti-fraud)
• Brass body epoxy-coated, hermetically sealed totaliser
• 12 pulse values, up to 2 outputs
• Stable materials for reliable reading over time

Reliability & anti-fraud

A water meter's reliability depends on its design: dry dial isolated from water, magnetic transmission between turbine and totaliser (which also protects against magnet fraud), hermetically sealed totaliser to remain readable over time, and brass body epoxy-coated or cast iron resistant to corrosion. These choices guarantee stable measurement and high longevity, even with slightly contaminated water.

Remote reading & control

Combined with pulse output, remote reading transforms metering into a management tool: readings are automatically sent to a building management system or software, without manual collection. You visualise consumption by point of use, distribute charges, spot overconsumption or leaks as soon as abnormal flow persists at night, and trigger alerts. This is the foundation of a water-saving and cost-control strategy.

DIMM metering range

This reference is part of the DIMM water metering range: single-jet, multi-jet, Woltmann and combination meters, pulse transmitters, protection filters, isolation valves and accessories combine to equip a complete metering point, from small domestic sub-meters to large industrial meters with remote reading.

Water saving & sustainability

Better measurement means better consumption: accurate metering and reliable remote reading reveal waste, encourage more responsible behaviour and quickly pay for the installation. Durable materials and a protected mechanism limit replacements, for a solution that is both economical and respectful of water resources.

Choosing the right meter

Meter selection is based on the flow rate to be measured and the pipe diameter (DN), temperature (cold or hot water), and measurement range (ratio R). Single-jet meters suit small domestic diameters, multi-jet offers better accuracy at low flow, Woltmann handles high flows with low pressure drop, and combination meters cover a very wide range. DIMM helps you size according to your installation.

Pulse output

Pulse output converts a volume of water into electrical signals: each pulse corresponds to a predefined volume (pulse value, adjustable among several values). Connected to a data logger, controller or BMS, it enables remote reading, leak alarm, distribution and proportional flow control. Depending on the model, two outputs (identical or different) and flow direction are available.

Installation & maintenance

Installation is on a full pipe, in the direction of the arrow, preferably horizontal to preserve accuracy (maximum ratio). Respect recommended upstream/downstream straight lengths and install a filter upstream to protect the mechanism. Isolation valves facilitate removal. Maintenance is minimal: periodic inspection and replacement at end of metrological life.
